St Peter noticed the back gates to Heaven were broken. AGAIN! He called Maintenance and complained. AGAIN! Then he set a watch over the gates to see if he could find out who was breaking them.
The watch-angel reported to him the next day. "Satan's little Imps are coming up at night and swinging on the gates and breaking them down."
Well, that was just the last straw for St Peter, so he called up the Devil and gave him an earful. "If you don't stop those imps from swinging on our gates and breaking them down, I'll ... I'll ... I'll SUE you!"
Satan calmly replied, "To sue me, you'll first have to find a lawyer. Do you really expect to find a lawyer up there? Hmmmm?"
